History
The school first opened in September 1965 as two separate institutions: St Patrick’s Boys Secondary Intermediate School, an all-boys school, and Our Lady’s Girls Secondary School, located in the adjacent building. These were later renamed St Patrick’s High School and Our Lady’s High School. In 1993, the two schools officially merged to form Holy Trinity College, a co-educational Catholic secondary school serving students aged 11–18. In 2023, construction began on a new £35 million facility at the rear of the existing Chapel Street site. Designed to accommodate up to 1,300 pupils, the new building includes modern classrooms, sports facilities, and a central courtyard. Construction was completed in October 2025, after which the original school buildings were demolished as part of Phase 2 of the redevelopment. == Academics ==
